At first glance, Relayted seems like a joke, a latterday album-length equivalent of the knowing cover versions with which indie bands used to pad out Peel Sessions: an album by a group of US alt-rock luminaries – Justin Vernon of Bon Iver and members of Digitata, Solid Gold and Megafaun among them – making a record in thrall to 10cc, 80s soft rock and R&B, replete with sax solos, on which every track proceeds at a stately 69 bpm, the speed at which I'm Not in Love went about its sultry business. But it turns out to be far more than a conceptual joke, digging deep into and expanding upon the (often inadvertent) aural weirdness of its source material. The results pitch beautifully crafted, poignant songs and heartfelt vocals against foggy, ethereal production. Vernon in particular is on shiver-inducing form on The Gaudy Side of Town, which builds from distorted human beatboxing and amplifier buzz into a quiet storm of early-hours regret. In paying homage, Gayngs have mapped out a sonic space entirely of their own, strange and murky and utterly alluring.
